Results of factor analysis after a varimax rotationa.

ALT, serum alanine aminotransferase; AST, serum aspartate aminotransferase; AP, alkaline phosphatase; TBIL, total bile acids; TP, total protein; GLO, globulin; HA, hyaluronic acid; LN, laminin; TGF-β1, transforming growth factor β1.a The loadings, eigenvalues, cumulative proportion of the total variance and a suggested interpretation are provided for the two factors. Only variables with loadings above 0.5 or below -0.5 were used in the interpretation (displayed in bold).b The cumulative proportion is the cumulative proportion of the total variance in the data. Because the variables are standardized to a variance of 1, the total eigenvalue is equal to 9 (number of variables).
